okay I can do this!
Vertex:
[tex]x = y {}^{2} - 6y + 8 \\ - y {}^{2} + 6y = 8 - x \\ - y {}^{2} + 6y = - x + 8 \\ y {}^{2} - 6y = x - 8 \\ y {}^{2} - 6y + 9 = x - 8 + 9 \\ (y - 3) {}^{2} = x + 1 \\ [/tex]
= (-1,3)
Focus:
[tex]x = y {}^{2} - 6y + 8 \\ x + 9 = y {}^{2} - 6y + 9 + 8 \\ x + 9 = = (y - 3) {}^{2} + 8 \\ x = (y - 3) {}^{2} + 8 - 9 \\ = x = (y - 3) {}^{2} - 1[/tex]
Directix:
[tex]x = y {}^{2} - 6y + 8 \\ x = y {}^{2} - 2y - 4y + 8 \\ x = y \times (y - 2) - 4(y - 2) \\ = x = (y - 2) \times (y - 4)[/tex]
I hope it's all right!
Please feel free to correct me if im wrong.
please give me brainliest.
